    Default AutoCAD error: eNullObjectId

    I am trying to import a shapefile into AutoCAD Map 3D 2012.
    I get the following error:

    "- AutoCAD error: eNullObjectID
    Can't open object for read. (3476 consecutive occurences)
    - AutoCAD error: eNullObjectID"

    I can attach to it through "Connect to Data" though.

    Anyone have a solution?

    I have not seen eNullObjectID with .shp files, so two questions:

    can you view the shape file with ESRI software?

    and can you post it here so we can look at it and try it on our setups?

    No solution for you... But that error is indicative of the .NET (perhaps ObjectARX?) API attempting (and obviously failing) to open an ObjectId to modify the associated entity.

    Yeah, I can open it with ArcGIS 10 and the old ArcView 3.3 - file was created in ArcGIS 9.3 according to the .xml file. The entities in the shape file are identified under shape as "PolyLineZ" - don't know if that will cause the problem. The import did bring in 3 lines - all of which had 'Z' attributes.

    Please zip and attach here the only .SHP file (without SHX/DBF and other garbage), I gotta give it a look-over, thanks.
